Aproveitamento de carcaça de aves silvestres como material didático

Abstract

Biological collections serve as essential repositories of biological material and associated data. They not only house specimens, but also valuable information about individuals and populations of each species, which can help to understand the impacts of changing biodiversity on society, caused by natural system dynamics or human-induced environmental damage. Such collections may receive inappropriate material for study purposes, such as incomplete or partially damaged specimens, which can still be used for numerous didactic purposes. In this study, carcasses of wild animals were used, particularly those from the Birds class, where feet, wing feathers and tails were used to create teaching materials, aiming to support practical classes, in addition to investigating the impact of these materials on teaching -learning. The animals were donated by the Wild Animal Screening and Rehabilitation – CETRAS after necropsy and subsequently processed at the Zoology Laboratory - LabZoo, located at the Federal Rural University of the Amazon – UFRA. The pieces were processed by removing wings and tails, for the collection of samples of primary, secondary and tertiary remiges, retrices and remiges, followed by the removal of the feet, ending with the application of 10% formaldehyde for fixation, making them suitable for classes practices. A semi-structured questionnaire was applied to students to verify the importance of these materials in academic training. It was concluded with this work that the use of these materials has a positive impact on the understanding of the animals' morphology and contributes to the theoretical-practical alignment, resulting in an academic and professional evolution regarding wild science.
